HARRY M. PFLAGER, OF ST. LOUIS, MISSOURI. DRAW-BAR SPRING-POCKET ATTACHMENT FOR METAL" CAR-UNDERFRAMES.

Spediflcation of Letters Patent. I Application filed December 4, 1905. flerlal llo. 290,157-

' Patented Aug. 7, 1906.

To all whom, it may concern:

Be it known that I, HARRY M. PFLAGER a citizen of the'United States, residing at St. Louis, in the State of Missouri, have invented a new and useful Draw-Bar S ring-Pocket Attachment for Metal Car-Un erframes, of which the following is a specification.

My invention relates to a block or filler interposed between the middle longitudinal metal sills of a car-underframe and adapted to form a draw-bar sprin -pocket in'combination or not with the body center late and as a separate but composite part 0 a body-' bolster extending therefrom to the outer lon- 'tudinal metal sills of the car, and has for its ob'ect to simplify construction and to enable t 's separate part of the bolster, with its combined draft-pocket, to be applied to abnormall deep sills, where the usual caststeel bo ster integral for the entire width of the car would be inapplicable.

The invention consists in features of novelty, as hereinafter described and claimed, reference being had to the accompanying drawings, forming part of this specification, whereon Figure 1 is a to plan view'of the longitudinal metal sills .0 a car-underframe (broken away) with my combined draw-bar springpocket and body center plate attached therethe separately-constructed end ortions othe .composite body-bolster of w 'ch the pocket forms the middle part; Fig. 2, a vertloal transverse section throu h the sills on line 2-2 in Fig. 1, showing the pocket and separate end portions of the bolster in front and side elevation, respectively, omitting the draft-gear; Fig. 3, a vertical longitudinal section to enlarged scale through the pocket and draft-gear on line 3 3 in Figs. 1 and 4; Fig. 4, a horizontal section through the pocket on line 4 4 in Fig. 3, showing the draft-gear in top plan view; Fig. 5, a vertical transverse sectlon throu h the middle longitudinal sills of the car ondine 5 5 in Figs. 3 and 4 and corresponding to Fig. 2, showing e the pocket in front elevation, omitting the draftear; Fig. 6, a vertical transverse section t ough the pocket and draft-gear on .5

line 6 6in igs. 3 and 4; Fig. 7, a view correspondmg to Fig. 6, showing a modification of the body center plate; and Figs. 8 and 9 views .corres ondin to Fig. 4, showing modifications oft e dr gear.

Like letters and numerals of reference denote like parts in all the figures.

a represents the middle ong tudmal metal sills, and?) the outer longitudinal sills 'of a.

car-underframe, which in the resent case are preferably channel-shaped 'in cross-section, as shown, but may be T, I or other suitable section. Between the middle sills a,

at a suitable distance from each end of the car, is arranged a hollow block or filler c, com-v of cast steel integral posed, preferabl throughout and aving its internal space or charn er (1 box-shaped, its two opposite sides 1 bearing externally respectively against the inner side'or upright'web 2 of the correspond-.

ing sill a. Each side 1 extends beyond the front and rear walls 3 and 4,'respectively, of the block cand form flanges 5 thereto, whereby the block 0 is rigidly secured to the sills a, b rivets 6, (or bolts.) Each side 1 is prefer ably formed at its lower part with an outwardly-projectingflange 7, which is adapted to underlap and bear against the bottom flange or under side of the corresponding sill a, to which it is rigidly fixed by rivets 6, (or

bolts.)

The interior space or chamber (1 of the block 0 is preferably divided at the middle longitudinally and parallel to the sills a into two compartments having a central vertical opening 10,- which extends entirely through the block 0 for the king-bolt. (Not shown.) Across the middle of each compartment 8, at right angles to the wall 9, is formed an upright wall 9, having a central transverse tubular opening 11, which is parallel longitudinally to the 81118 a, for the passage and play therethrou h of the draft-spring 12, having the usual ollowerplates 13 13, which normally bear against theinside face of the front and rear walls 3 and 4, respectively, of the block a, the two springs 12, with their respective followerplates 13 13, being arranged side by side in the same horizontal plane at a suitable distance a art, as shown.

. c is t e draw-bar end 14 adapted to pass throu formed-through the front wa h openin s 15, 3 of the lock having its forked inner- IOG c, and to butt against the front followerplates 13. To the top and bottom of the draw-bar e at each side of its longitudinal center corres on to the position-of-eaoh hits to owerlates13 13,is pivsp 12 Wit 5 ,otgil fiy a bolt (or pin) 16 t eiorkedends of a yoke-strap 17, which passes through the o ening andv ace or-chainberd of the blbck c and throug a correspondingo enlng 15 therefor intthe rear Wall 4 of the. lock c and straddles the follower-plates 13 13 and ring 12 in the usual well-known manner, all

ran ged to reduce a self-centering draw-bar and'operating substantially as described in 'the United States Letters Patent granted to me January 10, 1905, No. 779,559,'for an improvement in draft-gear 'for railroad-cars, and as particularly referred to in the modification described and shown by. Figs. 6 and 7 in the said patent.

l The block 0 is preferably provided on its under side with the body center plate 18, which is integral with the block 0; but, if de-.

sired, the center late 18 maybe'of se arate' construction an removably fixed to t e under side of the blocks by bolts, as shown in V Fig. 7, or, if desired, in cases where the block c is used 'as anl-auxiliary brace or filler between the sills a apart fromthe usual bodybolsterthe center plate 18 is omitted. When the center late 18 is integral with or omitted from the lilock c an opening 20 from each compartment 8 is formed through the botten g the entire wi tom of the block 0, as seen particularly in Figs. 3, 4, and 6, for enabling the followerplate 13 13 to be removed therefrom when required, the springs 12 being removable through the 'front openings '15, which are suitably sha ed for this purpose, as seen particularly in ig. 5.

Extending between each sill a and the corresponding outer sill b, opposite to each side 1 of the block 0 and separated therefrom by the web or body of the sill a, is abeam f, which is com osed of pressed, as shown, or cast steel of any desired cross-section and configuration and fixed at its ends to the sills a and b by rivets or otherwise, the beams which are alined to each other longitudinal y, forming the end portions and the block 0 the middle ortion of a com osite body-bolster exd th of the car.

Fig. 8 shows the block c, adapted to my improved draft-gear, in which the followerplates are dispensed with, as described in my application for Letters Patent filed November 9, 1905, Serial No. 286,576, for an improvement in draft-gear for railroad-cars. In

this case each compartment (corresponding to the compartment 8, before described) of the space or chamber 11 is divided transversely into two com artments 8 8' by a central upright wall 21 in its front side a ocket 22, which is opposite to a similar poc et 23,

the said parts of the draft gear being ar-- formed in the inner forked end of the drawbar 6, and on its rear side with a pocket 24, which is opposite to a similar ocket 25, formed in or attached to the close end of the yoke-strap 17. Within and between the pockets 22 23 and 24 25, respectively is placed a spring 12, whereb in the pulling and bufiing movements 0 the draw-bar e the s rings 12 are operated without :the use of f0 ower-plates, as fully described in my said a plication.

In ig. 9, the draft-gear seen in Fig. 8, two springs 12 which shows a modification of are arranged 'inlongitudinal alinement to-the draw-bar e in lieu of two springs 12" at each side thereof, as in Fig. 8, therebyenablin the draft-gear to be applied to a narrow bloc c in cases where the distance between .the middle sillsa of the car-frame .is limited -in which case the yoke-strap 17 is pivoted to the sides of the drawwbar e and;the openings through the walls 3, 4, and 21, corresponding to the o enings 15 and 15', before described,

the laterthe yoke-.-

the

enlarge according y for enabl' f ally-overhangin pivoted ends d stra 17 when t e latter is removedifrom bloc c to pass therethrough.

What I claim as my invention, and desire to secure by Letters Patent, is r 1. In a car-underframc, the combination with the middle longitudinalmetal sill'aand beams connecting the said sills to the outer longitudinal sills, of a hollow block'intermediate to and bearing against the-middle sills, and adapted internally to form a'housing for the springs and follower-plates of the draftgear, the said block havin suitable openings through its walls for the p ay of the draw+bar and its yoke-strap therethrough,.and.for'in serting and removin the s rings and follower-plates into, an from t e said housing, a body center plate integral with'the block on its under side, and means for fixing the block to the middle sills, substantially as described. 2. In a car-underframe, the combination with the middle longitudinal metal sills, and beams connecting the said sills to the outer longitudinal sills, of a hollow block intermediate to and bearing against the middle sills, and adapted internally to form a hous' for the springs ofthe draft-gear, the said b ock having suitable openings through its walls for the play of the draw-bar and its yokestrap therethrough, abody center: plate in.- tegral with the block, and means 'for'fixin the block to the middle sills, substantially as described.

3. In a car-underframe, the combination -with the longitudinal metal sills, of a hollow for the springs of a seli-centerin draft-gear,

and having an opening through t e front and rear Walls respectively of the said block, a draw-bar having bifurcated ends, a yokestrap pivoted to each of the said ends and adapted to play through the said openings, and means for fixing the block to the said sills, substantially as described.

In testimony whereof I have signed my HARRY M. PFLAGER.
